SOLDERlNG-TOOL.

SPECIFICATION forming part of Letters Patent No. 337,842, dated March 16, 1886.

Application filed January 18 1886. Serial No. 188,838. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD M. LANG, J r., of Falmouth, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in Soldering- Tools; and I do hereby declare that the following is a full, clear, and exact description of the invention, that will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in which Figure 1 is a side elevation of mechanism for forming the mouth of the can and holding the same while the can is being soldered. Fig. 2 is a side elevation of a can, a soldering-iron, and the ring a. Fig. 3 is a vertical section of a can and the ring a. Fig. 4 is a view of the under side of the ring; Fig. 5, an enlarged vertical section of the ring.

My improvement consists in so combining such a device with the circular soldering-tool as to render its use desirable and the work it produces practically perfect.

It consists of a ring, of iron or steel, or other suitable metal, which ring on the inner face or wall is provided with a shoulder, which preferably should be somewhat nearer the top than the bottom of the opening. (See Figs. 3, 4, and 5.)

a is the ring; I), the shoulder; a, the portion of the ring beneath the shoulder which is beveled slightly, and (Z the part of the ring above the shoulder, which is beveled in like manner. The shoulder b should be of a diameter slightly less than the diameter of the can to which it is proposed to apply it, or just sufficiently smaller to prevent the ring from sliding down over the can.

Fig. 1 shows a convenient method of using my device. h is atable provided with a fixed circular standard, 0, and the rotary plate 7c, which is fixed upon the top of the rod Z, which rotates freely in the journal w. Securely attached to the table is the post a, which is provided with the spring f, upon which rests the arm One end of the arm 9 is pivoted to the post 6, while to the other end is attached the strap j, which holds the ring a. Fixed to the under side of the arm 9 is the former 1), which should be slightly larger than the can to be operated upon, and which is beveled at the lower end. The rod i connects the arm 9 with the treadle m, which is pivoted to the floor at n.

The operation of the device is as follows: The cover having been put in place w1th1u the walls, the ring a is placed upon the top of the can A,'the shoulder b resting upon the edge of the wall of the can. (See Fig. 3.) One or more pieces of solder-wire are then placed upon the seam between the wall of the can and the edge of the cover, and the solderingtool 8 applied. (See Fig. 2.) One or more rotations of the tool spread the solder evenly over the seam, the wall (1 of the ring preventing any overflow of solder. The operation of the device shownnn Flg. 1 is equally simple. The can A, without the cover, is placed upon the standard 0, and centered beneath the former p. The lever in is depressed, and the beveled part of the former forced into the can, thereby straightening the walls, and preparing them to receive the cover. The lever being released, the can is then placed upon the table 70, and centered beneath the ring a, which is brought down upon the walls of the can, and the cover forced into place, the beveled portion d of the ring serving to guide the cover between the walls of the can. The solder is then applied by the soldering-tool as before, the can or the tool, or both, being rotated.

Vhat I claim as my invention is- 1. The combination of a soldering-tool and a ring of metal having a shoulder upon the inner wall thereof, substantially as described.

2. As a device for soldering the covers of cans, the combination of a ring of metal having on its interior wall a shoulder slightly smaller than the wall of the can to be soldered,and a circular soldering-tool the diameter of which is such as to allow its free rotation within the shoulder.

3. The combination of the standard 6, lever or arm 9, springf, table h, and ring a, as and for the purposes described.

4. The combination of the table h, standard 0, arm g, and ring a, as and for the purposes set forth.

5. The combination of the table h, standard 6, arm 9, ring a, and rotary table is, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 9th day of January, 1886.
